per call · USD Coin on Base
Canonical harness tear-sheet — one call returns totals (fires / boundary / silent / first-ever), top-5 fires by confidence, first-ever prints (5-year rarity), boundary watchlist (near-fire ranked by distance-to-trigger), and silent fade setups. Every setup carries plain-English composition (via ref.metric_display_labels) so responses never leak raw metric_id strings. Priced cheap so polling patterns stay economically viable — every MCP skill instructs Claude to call this FIRST as the canonical orientation. Scope: apex (BTC/ETH/SOL default), all (33-asset curated universe), or asset:{SYMBOL} for single-asset lens.
